A 120 V wire-feed welder for MIG and flux-cored fabrication, selected as stock 907838. Auto-Set presets wire diameter and material thickness, while manual mode gives direct voltage and wire-speed control. The machine provides 30–140 A output, with 100 A at 60% duty and 80 A continuously. The factory package includes an MDX-100 gun, work lead, regulator and gas hose; a separate spool gun adds aluminum-wire capability.
